Rainbow chicken and commercial meat

Assalaamu alaykum,Dear Mufti,
the day after tomorrow marks 1 month since your letter to sanha exposing the Shari violation,
cruel treatment of shackling etc
A) Stunning
B) inability to detect and remove dead birds accurately
C) disgusting scalder process of dipping into hot water with all impurities & meat etc
What is the current Fatwa on commercial meat that is produced where a,b & or c are a standard norm?
